新白沙沱長江大橋連接大渡口和江津，是重慶至貴州的重要通道。 最近，這座擁有三個“世界第一”記錄的橋樑建成了。一起來看看。

The New Baishatuo Yangtze River Bridge connects Dadukou and Jiangjin and is an important channel from Chongqing to Guizhou. Recently, this bridge — with three “world’s first” records — was built up. Let’s have a look.

見證三項“世界第一”紀錄

Set three “world’s first” records

新白沙沱長江大橋全長5.32公里，主橋長920米。 這是渝黔鐵路穿越長江的重要通道和重要樞紐。

這座橋樑載有三個“世界第一”的紀錄：是世界上首座六線鐵路橋，也是首座雙層鐵路橋，更是世界上延米載荷最大的橋樑。

The whole New Baishatuo Yangtze River Bridge is 5.32 kilometers long, with the main bridge being 920 meters long. It is an important passage and critical control work for the Chongqing-Guizhou Railway to cross the Yangtze River.

The double-deck six-track railway bridge includes two tracks for the Chongqing-Guizhou Passenger Railway, two tracks for the Chongqing-Guizhou Freight Railway and two tracks reserved for the Chongqing-Hu'nan Passenger Railway.

The designed speed of the four-track passenger railway on the upper deck is 200km/h, while that of the double-track freight railway at lower deck is 120km/h. After the Chongqing-Guizhou Railway is opened, it will only take a minimum of 16.56 seconds for trains to pass over the bridge.

大橋穿“雨衣”延長使用壽命

Bridge wearing “raincoat” to extend service life

通常在我們的印象中，只有公路和高速公路的橋樑是用瀝青鋪成的，但是這個橋樑也是用瀝青鋪成的。

這是一座鋼桁架斜拉橋。鋼桁架暴露在外，容易受到酸雨腐蝕。 因此，新型環氧瀝青混凝土（類似“雨衣”）被用來延長橋樑的使用壽命。

Usually in our impression, only road and highway bridges are paved with asphalt, but this bridge is also paved with asphalt.
This bridge is a steel-trussed cable-stayed bridge. The steel trusses are exposed and easily corroded by acid rain. Therefore, the new-type epoxy asphalt concrete (similar to a “raincoat”) is used to extend the service life of the bridge.
